The front cloth piece is a bit lacking and I'm thinking of adding in an Ultramarines symbol, possibly something like this... (30 second photoshop mockup incoming!)
But! Also! Another Sternguard enters! I kinda love this guy. The bionic head is from the Forgeworld character set and the ridiculously oversized belt piece you'll probably recognise from the Marneus Calgar model.
He's about two thirds done, a lot of tidy up work, basing, drill that bolter barrel etc etc.
